Abstract

See full text

A segmented retractable seal is provided in a stator of a turbine by which a rotor seal is arranged radially and axially movably in a groove formed in the stator of the turbine and is connected with a mechanism which retracts it away from the rotor of the turbine in a radial direction. The groove formed in the stator of the turbine contains an outer partial groove formed on the inner surface of the stator and an inner partial groove formed in the body of the stator and connected with it, its width being smaller than or equal to that of the outer partial groove. A head of the seal is arranged in the inner partial groove, and a comb of the seal is arranged in the outer partial groove. The head of the seal and the comb of the seal are connected by a neck of the seal.
